Just going to add another 2c here, regardless of whether anyone wants it or not.
The whole point of putting oneself on display has been missed here. It's not just about showing off your beloved to the whole world, a huge component of it is also taking criticism. Know which to reject (aww bruu, put a V8 in it!) and what to consider as good advice. Here in NZ, it's difficult to actually find constructive criticism as all crit is worded harshly. It's part of our culture.
FURTHERMORE, remember that the presence, the stand and the people are as much on display as the cars. If anything what you say before, during and after the event has a million times more impact than the cars on display.
In short, any attitude you bring to the table is the opinion of the whole club that people will take home with them. If it's a startup club, consider every word you say extremely carefully before you make it public. You don't want people to remember 'The nice Subarus owned by bitter people'. It would severely damage the club's chances of spreading and becoming successful. Attitude is everything. Keep a positive outlook and a positive attitude, and things will be looking up.
